I wonder if anyone can tell me the timing specs on a 140hp Chrysler model # 1408H2D<br />serial # 1202<br />I think it is a 1983 model engine.<br /><br />Thanks
The manual that I have shows specs for the Force 125hp and 150hp.<br /><br />For the 150hp static timing is 32 deg BTDC and dynamic timing of 30.<br /><br />It is 34 and 32 for the 125hp.<br /><br />I guess I will set it to 32 btdc as nobody seems to know anything about these 140hp chryslers.
The old girl would run at about 4400 rpm with some hesitation and a slight miss off and on.<br /><br />Checked the plugs cyl # 2 and 3 are fouled.<br />Cleaned up the plugs but still only runs at 4400 rpm. Also drained the tank and put in fresh gas/mix.<br /><br />Shined a light into the cylinders and they are caboned up pretty bad.<br /><br />Ran some Sea Foam Deep Creep through it yesterday and now she runs at 4800 to 5000 rpm.<br /><br />Problem is she is still fouling # 2 and 3 plugs and missing slightly.<br /><br />Any ideas anybody?
Checked compression on all cylinders.<br />#1 is 150<br />#2 is 150<br />#3 is 155<br />#4 is 150<br /><br />Don't know what the original compression specs were on it but the motor has been sitting for awhile and had some really old gas run through it.<br /><br />I will take it out again in the next couple of days and see what it does after putting in a new set of plugs.
Crankshaft timing should be 30?
BTDC on 135 hp models manufactured
prior to 1972 and all 140 and 150 hp
models. When setting piston position
with a dial indicator, the equivalent
reading should be 0.254 in. BTDC on 140
hp models and 0.246 in. BTDC on all
other models.
